-
An exhaust manifold is a metal unit that collects exhaust gases from the engine. It is part of a network called the exhaust system.
Description
The exhaust manifold is usually designed as a network of pipes connected to the engine.
How It Works
The exhaust manifold collects the exhaust gases from the engine and routes them to the exhaust pipe. This is meant to eject the gases out of the vehicle.
Relation with Engine Cylinders
The number and design of the exhaust manifold depend on the number or manner of cylinder heads the car's engine possesses. Linear engines normally have one exhaust manifold; V-shaped engines--like V6s (six cylinders) and V8s (eight cylinders)--have an exhaust manifold for each cylinder head.
Make
Exhaust manifolds are usually made of tubular steel, lightweight aluminum or cast iron.
Significance
Without the exhaust manifold, the car's engine cannot eject exhaust through the exhaust pipe. Getting rid of waste is essential to the volumetric efficiency or optimal performance of the engine.
